To be honest, I haven't seen anything too crazy when I've been there aside from this 458 and 650S, but Dustin has seen some great stuff around Ballantyne. Sadly he hasn't posted in a while, but a lot of his spottings were from either Ballantyne or Southpark. He has caught the elusive 997.2 GT3 RS and 458 Speciale at the Morrison YMCA, both of which are owned by the same person. There's also a yellow 991 GT3 RS in Ballantyne.
Patrick, I rarely go to Ballantyne either, but there are a ton of exotics there. This was in the business park off of Johnston Rd and I-485. I have heard that this 458 is daily driven and is always parked there, but I hadn't heard anything about the Mac so I guess I was just fortunate that it happened to be parked there when I drove through. There are huge houses all over Ballantyne, so there are a ton of exotic cars there. I know of several GT3/RSs, 458/Speciales, 488 GTBs, Gallardos, Huracans, Aventadors, and the like around there, so it's just a matter of spotting them.
